An organization represents a group of users on Redivis who are uploading and managing datasets. In order to gain access to these organizations' datasets you'll need to become a member of the organization and potentially fill out additional requirements outlined in the dataset's permission group.
Organizations have their own homepage which has a portal for searching all of their datasets, and any public projects which contain their datasets. They also have advanced tools like collections for managing a large amount of complex data.
To navigate to an organization's homepage you can go to redivis.com and click on any organization's name.
